Vehicle-mounted road positioning radar device with double-wave and implementation method thereof

Abstract

The invention relates to a vehicle-mounted road positioning radar device with double-wave and an implementation method thereof, which is capable of detecting and positioning the precise position of the vehicle rapidly, accurately, repeatedly, and freely from environmental impact, and capable of transmitting data to a management platform through the mobile internet. The radar device comprises a radar positioning control unit, a communication unit, a power supply unit, a mobile phone application, and a passive digital sensor which is arranged in a related to-be-detected positioning subject object to receive energy from electromagnetic waves and capable of bi-directional communication. The radar positioning control unit comprises two groups of identical electromagnetic wave generating circuits and two groups of demodulation circuits thereof connected to an antenna A and an antenna B respectively, wherein the antenna A and the antenna B are arranged under the vehicle chassis; a control unit is composed of an ATmega8 single-chip microcomputer and a corresponding auxiliary circuit; the radar positioning control unit is connected to the communication unit and the power supply unit in sequence; the two inputs of the power supply unit are connected to the vehicle battery for supplying power thereto; and the mobile phone application is connected with the communication unit through a WiFior a Bluetooth wireless network.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, and relates to a vehicle-mounted dual-wave road positioning radar device and an implementation method thereof. Background technique [0002] In recent years, with the rapid development of the automobile industry, the performance of its products has been continuously improved, the styles have been constantly changed and updated, and the social ownership has continued to grow, far exceeding the development of urban roads and the increase of effective berths and parking lots. On the other hand, the rapid development of electronic communication technology, electronic sensor technology, and satellite navigation technology, especially the rapid development of mobile Internet, provides a new way for automobiles and management platforms, automobiles and roads, automobiles and berths, parking lots and Effective linkage of related facilities offers possible solutions. There are many existing ...

AI Technical Summary

Problems solved by technology

There are many existing Internet of Vehicles products, but their functions are focused on communication, navigation, rough location measurement, and vehicle condition parameters, and it is impossible to link the car with a certain lane, a certain berth, or a certain parking lot on the road.

If the car is driving on a more complex overpass, the existing satellite navigation prompts will not be able to provide accurate prompts, giving people the feeling of being in the fog and not knowing what to do
